Hardware development and manufacturing · Shenzhen
You bring the product. We handle the rest: engineering partners, prototypes, factories, quality and shipping. You work directly with Brian Barrett, 13+ years making products in China, and you can talk to every team and factory building your product.
Camera and sensor devices are our specialty.

The hard part
Most hardware delays and cost overruns come from four mistakes. We have seen each one up close, and we keep them off your project.
We redesign for manufacturability so it can actually be built at volume, not just work once on a bench.
We vet suppliers in person (capability, capacity, and track record) before a cent moves.
On-site inspections and pilot runs catch defects before they ship by the thousand.
Clear quoting, tooling oversight, and a build plan that holds, managed on the ground while you sleep.
What you get
One accountable lead, the right specialists for your product, and a clear view of who is building it.
Lavigne Labs is a small, founder-led team. Brian leads every project himself. For engineering and production we bring in partners we have vetted over 13 years: design houses, camera and electronics factories, and suppliers. You get one contract, one accountable lead, and the right specialists for your product.
Specialty
Cameras are where hardware gets hard: lenses and image sensors, IMUs, synchronisation and calibration, heat in a small enclosure, and factories that can build all of it the same way every time. It is where we do our best work.
We have worked on several egocentric data-capture projects: head-worn camera rigs that record how people use their hands, to train robots and AI.
How it works
Every engagement de-risks the next step before you commit to it — no leaps of faith, no surprises.
We start with your design, prototype, or idea. We assess what's needed to manufacture it well and flag risks early.
We match your project to the right vetted Shenzhen engineering team for your product, schedule, and budget.
A pilot run plus hands-on quality control proves the process before you commit to full volume.
Production ramps with ongoing oversight on quality, cost, and timeline. Your hardware, in the field.
Working together
Three ways to work with our team, depending on where your product is. Lavigne Labs leads every one of them, and Brian Barrett is your first contact.
Real hardware in your hands, fast. Concept to working prototype, then quick rounds of testing and refinement. This is the hook: you learn more in a few weeks of building than in months of planning.
Take a proven prototype through design for manufacturing, tooling, pilot runs and scale-up, with a vetted Shenzhen engineering team matched to your product.
Already in production? We help with supplier follow-up, on-site quality control, changes and second-source decisions, so units keep shipping on spec.
We move fast. Speed costs money; we spend it where it saves weeks.
Prototyping is where we start, because real hardware in your hands beats any plan. Once you are in production, getting the lowest unit cost at volume is a goal we are glad to work toward with you. In development, we would rather spend wisely to save weeks than shave pennies and lose months.
Hardware doesn't get built over a video call. We are in the factories in person, reading schematics, walking the line, and catching problems before they ship by the thousand.
Selected work
Most client work stays under NDA, so these are builds we can show: boards, mechanisms and products from our own bench. The same design, PCB and mechanical work goes into every client project.

A sliding stand for a digital microscope: an X/Y table under the workbench with linear rails and cable chains, so the microscope glides into place with a push.

PyBikeBrain, a modular microPython board for E-bikes, inspired by the pyBoard, with stackable layers for serial, power and more.

An articulated camera arm of carbon fiber tubes, polished steel spheres and red aluminum pressure plates, inspired by Robin Renzetti's design.

A reproduction of Input Club's open source K-type keyboard, built to study manufacturing and find ways to cut BOM cost.

A whiteboard plotter inspired by draw bots, built on plywood with linear rails, a 3D printer control board and open-source software.

About
Lavigne Labs was founded by Brian Barrett, a hardware engineer with 13+ years in China. He ran an LED factory for Black & Decker for six years, and worked with two EV startups building tilting vehicles and electric motorcycles.
Here is how we work. Lavigne Labs is the face and the accountable lead. Each project is matched to a vetted Shenzhen engineering team, design-led or production-integrated depending on what you need, with 40+ engineers across our partner teams. Brian is your first contact and puts his reputation on the results.

See all questionsLavigne Labs is the face and the accountable lead on every project, and Brian Barrett is your first contact. We match your project to a vetted Shenzhen engineering team, design-led or production-integrated depending on what you need. Most projects start with a prototype sprint, move into development to production, and continue with production support. You can join at any stage.
We move fast. Speed costs money; we spend it where it saves weeks. Prototyping is where that pays off most: fast iterations, quick-turn parts, and decisions made in days. Getting the lowest unit cost at volume is a goal we're glad to chase in production. In development, we'd rather spend on learning quickly than shave the budget and lose weeks.
We work best with funded startups and teams with a completed Kickstarter, and we love working with them. Lavigne Labs leads every project, matched to a vetted Shenzhen engineering team.

Yes — that's the whole point. Electronics, prototyping, and production are usually split across different people and vendors, with handoffs where things break. Our team covers the full path, from schematic to shipped units, so nothing gets lost in translation.
Compact, real-world devices — PCBs and electronics, wearables, cameras and optics, LED and sensor-driven gadgets, and the enclosures around them. The badge and toys in the Work and Play sections are good examples of the form factors and bring-up involved.
Often the best fit. Early hardware is exactly where one accountable team that can both design it and get it built saves the most time and money, instead of stitching together a designer, a sourcing agent, and a factory who don't talk to each other. Funded startups and teams with a completed Kickstarter are who we work best with.
We're based in Shenzhen and in the factories in person; that's the advantage. We work with teams anywhere in the world. The design can happen over a call, but the build, the vetting, and the quality control happen here, in person.
Because a prototype proves the idea, not the process. Getting a design ready to manufacture — DFM — is the buyer's job, not the factory's, and skipping it is the most common way first runs blow up. Closing that gap is a big part of what we do.
